![]() | ![]() タイトル: Substrate adaptors are flexible tethering modules that enhance substrate methylation by the arginine methyltransferase PRMT5. 著者: Cyrus Y Jin / Moritz Hunkeler / Kathleen M Mulvaney / William R Sellers / Eric S Fischer / ![]() 要旨: Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine marks. PRMT5 uses substrate adaptors such ...Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine marks. PRMT5 uses substrate adaptors such as pICln, RIOK1, and COPR5 to recruit and methylate a wide range of substrates. Although the substrate adaptors play important roles in substrate recognition, how they direct PRMT5 activity towards specific substrates remains incompletely understood. Using biochemistry and cryogenic electron microscopy, we show that these adaptors compete for the same binding site on PRMT5. We find that substrate adaptor and substrate complexes are bound to PRMT5 through two peptide motifs, enabling these adaptors to act as flexible tethering modules to enhance substrate methylation. Taken together, our results shed structural and mechanistic light on the PRMT5 substrate adaptor function and the biochemical nature of PRMT5 interactors. | ||||||

They are numbered as residues 109-114. However, this region could actually be 97-102, or any stretch of GRGRGR between residues 97 and 114. |
